摘要
三洋坝金矿床位于西成铅锌矿田西部,秦岭褶皱系西秦岭海西褶皱带东段,矿体赋存于中泥盆统西汉水组地层中,受层位和层间裂隙控制,含矿岩石为石英脉及斑点状绢云母千枚岩和变砂岩,石英脉发育时,矿化强烈。为层控的热水沉积-变质矿床。
The Sanyangba sold deposit is located in the west part of Xi-Cheng （Xihe County-Chengxiang County） lead-zinc orefield, and the east district of the West-Qinhng variscian folded belt of Qinling fold system, ore bodies occur in the strata of Xihanshui group of middle-devonian, bound by stratohorizon and interlayer fissures, the ore-bearing rocks are quartz veins, spotted sericite-phillites, and meta-sandstones. Mineralization is strong with the development of quartz veins. It is a strata-bound hydrothermal deposition-metamorphism deposit.
